Another big cause of the msncon32.dll errors is the registry database of Windows. The “registry” is a central database which stores all the settings, information and options for your computer, and is where Windows keeps many vital settings that it requires to run. It’s often the case that a lot of registry settings become damaged and corrupted, leading your PC to become unable to read a lot of the files which it needs from the database, causing a variety of errors. Unbeknown to many people, the “registry” is actually one of the biggest causes of “.dll” errors on your PC, as this database stores a list of all the .dll files on your system. It’s often the case that this list becomes damaged, leading Windows to show various DLL errors.

To fix this problem, you should use a ‘registry cleaner’ to scan through your PC and fix any of the damaged or corrupt settings that are inside it. You can see our recommended registry cleaner below:
